optical magnetic recording medium, a semiconductor memory, or the like. Further, the
program executed by the CPU 11 may be downloaded to the image display apparatus 1
by using a communication section such as the Internet.
[0043] In the embodiments above, the term "processor" refers to hardware in a broad sense.
Examples of the processor include general processors (e.g., CPU: Central Processing
Unit) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application
Specific Integrated Circuit, FPGA: Field Programmable Gate Array, and programmable
logic device).
[0044] In the embodiments above, the term "processor" is broad enough to encompass one processor
or plural processors in collaboration which are located physically apart from each
other but may work cooperatively. The order of operations of the processor is not
limited to one described in the embodiments above, and may be changed.
[0045] The input unit 20 is an apparatus such as a pointing device by which the user inputs
an operation.
[0046] For example, in a case where the input unit 20 is a mouse or the like, the user can
designate a position on a screen of the display unit 40, a displayed image, or the
like by performing a cursor movement operation or a click operation.
[0047] Further, in a case where the input unit 20 is a touch panel or the like, the user
can designate a position on a screen or a displayed image by performing an operation
of touching the touch panel with a finger or the like or an operation of maintaining
the touched state of the finger or the like for a longer time than a predetermined
time. In this case, the input unit 20 is provided integrally with the display unit
40.
[0048] In addition to the apparatus such as the pointing device described above, a keyboard
or the like for performing a key input operation may be provided as the input unit
20.
[0049] Fig. 2 is a diagram illustrating an example of an operation screen of the image display
apparatus 1 to which the present exemplary embodiment is applied.
[0050] The display unit 40 displays an operation screen 400, which is a screen for accepting
an operation by the user, as illustrated in Fig. 2. In other words, the operation
screen 400 is an area in which an instruction image and the like for accepting an
operation of the user are arranged. The document may include an image in addition
to a text, or may include only an image without including the text.
[0051] On the operation screen 400, in addition to a document icon 410, a display instruction
button 411, a confirmation image 420, a toolbar 430, and the like are displayed.
[0052] The document icon 410 is an example of an instruction image for accepting an instruction
of the user. The instruction of the user includes selecting, browsing, moving a storage
location, moving a display location of an instruction image, and the like for a document.
Further, the display instruction button 411 is an image for giving an instruction
related to display of the confirmation image 420. The confirmation image 420 is an
image for allowing the user to confirm a content of the document related to the instruction
image such as the document icon 410. The toolbar 430 is a collection of instruction
units prepared to simplify operations on electronic documents by the user. Examples
of the operation for this electronic document include operations of saving, printing,
rotating, searching for, and encrypting the electronic document, an operation of bundling
two or more electronic documents, and the like.
[0053] In the present exemplary embodiment, a size of the operation screen 400 on the display
unit 40 can be changed by an operation of the user. Further, it is also possible to
obtain a rectangular shape with an aspect ratio different from Fig. 2, by changing
a shape of the operation screen 400 by the operation of the user.
[0054] The document icon 410 is an instruction image for accepting an instruction of the
user on the document. The document icon 410 may be a thumbnail image for checking
at least a part of a content of a file managed by file handling software. This thumbnail
image is simply displayed as a reduced image of the original image, for example, in
a case where the corresponding file is image data. In a case where the corresponding
file is document data having a plurality of pages, a representative page such as the
first page is displayed as the reduced image. The document icon 410 displayed as a
thumbnail image functions as an icon for opening the corresponding file, for example.
[0055] In a case where a document displayed as a thumbnail image consists of a plurality
of pages, an image (not illustrated) for accepting a change of the display page from
the user may be displayed in a state of being associated with the document icon 410.
In the present exemplary embodiment, the "page" is a set of pieces of data displayed
as one surface on the operation screen 400 at a time.
[0056] The document icon 410 may be a tray used for the user to deliver an electronic document
to a third party, a folder used for storing the electronic document, an electronic
document, or the like represented by a pictogram.
[0057] The display instruction button 411 is an image for accepting an operation instructing
display of the confirmation image 420 by the user, and is an example of an instruction
button that is an image for accepting an instruction related to the display of the
confirmation image 420. This instruction button is displayed in a state of being associated
with the document icon 410. Further, instead of the display instruction button 411
illustrated in Fig. 2, a maintenance instruction button (which will be described below
with reference to Fig. 10) corresponding to an instruction to put the confirmation
image 420 in a display maintenance state may be displayed.
[0058] In the present exemplary embodiment, the display instruction button 411 and a maintenance
instruction button 412 are displayed so as to be superimposed on an upper right corner
portion of the document icon 410. In this case, it is preferable that the display
instruction button 411 and the maintenance instruction button 412 are displayed so
as not to reduce visibility of the document icon 410, for example. For example, the
display instruction button 411 is displayed to be smaller than the document icon 410.
Further, the display instruction button 411 is displayed semi-transparently so that
a superimposed portion on the document icon 410 can be seen through.
[0059] The confirmation image 420 is an image for allowing the user to confirm a content
of the instruction image. The confirmation image 420 is displayed without starting
a new program in a case where the user performs an operation to instruct the display.
In the example in Fig. 2, an enlarged image of a thumbnail image of the document is
displayed as the confirmation image 420 for confirming the content of the document
corresponding to the document icon 410. A resolution of the thumbnail image displayed
as the confirmation image 420 may be higher than a resolution of the thumbnail image
displayed as the document icon 410.
[0060] In addition, as illustrated in Fig. 2, a text 440 such as a name of a file or a function
corresponding to the document icon 410 may be displayed in association with each image,
on the operation screen 400. Further, the text 440 may be displayed in association
with the confirmation image 420.
[Functional Configuration of Image Display Apparatus 1]
[0061] Next, a functional configuration of the image display apparatus 1 will be described.
[0062] Fig. 3 is a block diagram illustrating an example of the functional configuration
of the image display apparatus 1. As illustrated in Fig. 3, the image display apparatus
1 includes an operation determination unit 101 that determines whether or not an operation
is performed by the user, a distance determination unit 102 that determines a distance
between two points on the screen of the display unit 40, a display control unit 103
that controls contents to be displayed on the display unit 40, an instruction button
output unit 104 that outputs an instruction button to the display unit 40, a confirmation
image output unit 105 that outputs the confirmation image 420 corresponding to an
instruction image to the display unit 40, and an image acquisition unit 106 that acquires
an image to be output to the display unit 40.
[0063] The operation determination unit 101 determines whether or not a user operation is
performed via the input unit 20 on the operation screen 400 (see Fig. 2) . The user
operation is, for example, an operation of designating an image, an icon, a position,
or the like on the operation screen 400, a scroll operation, a key input operation,
or the like.
[0064] The distance determination unit 102 determines a distance from the instruction image
(see Fig. 2) such as the document icon 410 displayed on the operation screen 400 to
an end of the operation screen 400 in an up-down direction and a right-left direction.
More specifically, a distance from each side of the instruction image in the up-down
direction and right-left direction, a predetermined specific area on the instruction
image, a reference position predetermined on the instruction image, or the like to
the end of the operation screen 400 in the up-down direction and right-left direction
is determined. Details of the specific area and the reference position will be described
below with reference to Fig. 11.
[0065] Further, the distance determination unit 102 according to the present exemplary embodiment
determines a position of the instruction image on the operation screen 400, based
on the distances from the instruction image to the end in the up-down direction and
right-left direction
[0066] The display control unit 103 controls a display mode of the document icon 410, the
confirmation image 420, the toolbar 430 (see Fig. 2), or the like based on a content
determined by the operation determination unit 101 and the distance determination
unit 102. The display control unit 103 controls a position at which the document icon
410 is displayed, for example, based on the content determined by the operation determination
unit 101. Further, for example, a position and a size in which the confirmation image
420 is displayed are controlled based on the content determined by the distance determination
unit 102.
[0067] Further, the display control unit 103 controls to display an image captured by the
image acquisition unit 106 as the instruction image. For example, a thumbnail image
is taken from the image acquisition unit 106, and controlled to be displayed as the
document icon 410 for opening the corresponding file.
[0068] The instruction button output unit 104 outputs an instruction button for giving an
instruction related to display of the confirmation image 420, such as the display
instruction button 411 for giving an instruction to display the confirmation image
420 or the maintenance instruction button 412 for giving an instruction to maintain
the display of the confirmation image 420, to the display unit 40. This instruction
button is displayed in a state of being associated with an instruction image such
as the document icon 410.
[0069] The confirmation image output unit 105 takes out the confirmation image 420 acquired
by the image acquisition unit 106, based on the determination of the operation determination
unit 101 that the display of the confirmation image 420 is instructed. The confirmation
image output unit 105 outputs the confirmation image 420 corresponding to the document
icon 410 instructed by the user to the display unit 40 without starting a new program.
[0070] The image acquisition unit 106 acquires an image to be displayed on the display unit
40, such as an instruction image such as a document icon 410 or another icon, an instruction
button output by the instruction button output unit 104, a confirmation image 420
output by the confirmation image output unit 105, and the like. For example, a thumbnail
image is generated and acquired as the document icon 410, based on the document stored
in the secondary storage unit 30. Further, for example, an image already stored in
the secondary storage unit 30 is taken out and acquired as the confirmation image
420.
[0071] The image acquired by the image acquisition unit 106 is stored in a state of being
taken out as the instruction image, the instruction button, and the confirmation image
420. The function of storing this image is realized by the non-volatile memory 14
(see Fig. 1).

In the present exemplary embodiment, the display instruction button 411a or a maintenance
instruction button 412a is an example of a specific image displayed corresponding
to the specific area 416. Since the display instruction button 411a and the maintenance
instruction button 412a correspond to the specific area 416 smaller than the document
icon 410a, the document icon 410a is not completely covered.
[0083] Further, the display area 421 illustrated in Figs. 6A to 9 is an area secured for
displaying the confirmation image 420a, and is located in any direction of the up-down
direction and the right-left direction with respect to the specific area 416. By displaying
the confirmation image 420a in the secured display area 421, the confirmation image
420a is displayed in any direction of the up-down direction and the right-left direction
with respect to the specific area 416. The confirmation image 420a does not have to
be displayed over the entire display area 421. Here, the fact that the confirmation
image 420a is displayed in one direction with respect to the specific area 416 means
that the confirmation image 420a is located so that at least a part of the specific
area 416 is not superimposed on the confirmation image 420a in a direction opposite
to the one direction with respect to the confirmation image 420a. For example, in
a case where the confirmation image 420a is displayed in a right direction with respect
to the specific area 416, at least a part of the specific area 416 is located in the
left direction of the confirmation image 420a not to be superimposed on the confirmation
image 420a. Since the specific area 416 is a predetermined area on the document icon
410a, the document icon 410a is displayed so that at least a part of the document
icon 410a is not superimposed on the confirmation image 420a.
[0084] The maintenance instruction button 412a illustrated in Fig. 10 is an image for accepting
an instruction of the user who maintains the display of the confirmation image 420a.
The maintenance instruction button 412a is displayed at a position at which, for example,
the display instruction button 411a is displayed in a case where the display instruction
button 411a is designated and the confirmation image 420a is displayed. A state in
which the display of the confirmation image 420a is maintained by an operation of
the user such as the instruction to the maintenance instruction button 412a is defined
as the display maintenance state.
[0085] Next, the description is continued with reference to the flowchart illustrated in
Fig. 4.
[0086] First, the operation determination unit 101 illustrated in Fig. 3 determines whether
or not any of the document icons 410 is designated based on an operation via the input
unit 20 (step S501). In the present exemplary embodiment, the operation determination
unit 101 determines the operation of moving the cursor 200 so as to indicate any of
the document icons 410, as designation of the document icon 410. For example, a mouse
over operation or the like of locating the cursor 200 over the document icon 410 is
determined as the designation of the document icon 410. In the example in Fig. 5A,
since the cursor 200 is not located over any of the document icons 410, it is determined
that the document icon 410 is not designated.
[0087] In a case where the document icon 410 is not designated in step S501 (NO in step
S501), the process waits until the document icon is designated. In a case where the
document icon 410 is designated (YES in step S501), the instruction button output
unit 104 outputs and displays the display instruction button 411 (step S502). For
example, in a case where there is a mouse over operation of locating the cursor 200
over the document icon 410a illustrated in Fig. 5A, the display instruction button
411a is displayed as illustrated in Fig. 5B (step S502).
[0088] Next, the operation determination unit 101 determines whether or not the display
instruction button 411a is designated based on an operation via the input unit 20
(step S503) . The operation determination unit 101 according to the present exemplary
embodiment determines, for example, that a mouse over operation on the display instruction
button 411a is the designation on the display instruction button 411a.
[0089] In a case where the display instruction button 411a is not designated (NO in step
S503), the process waits until the display instruction button 411a is designated.
In a case where the display instruction button 411a is designated (YES in step S503),
the display control unit 103 determines one direction for displaying the confirmation
image 420, based on a distance from the document icon 410a determined by the distance
determination unit 102 to an end of the operation screen 400 in the up-down direction
and the right-left direction (step S504). A procedure of determining one direction
for displaying the confirmation image 420 based on the determination of the distance
determination unit 102 will be described in detail below with reference to Figs. 11
and 12.
[0090] Subsequently, the display control unit 103 secures an area from the predetermined
specific area 416 determined on the document icon 410a to an end of the operation
screen 400 in one direction as the display area 421 for displaying the confirmation
image 420 (step S505).
[0091] Fig. 6A illustrates an example of the display area 421 in a case where a right direction
is determined as one direction in step S504. In the present exemplary embodiment,
the display instruction button 411a is displayed in association with a specific area,
and an area from the display instruction button 411a to an end of the operation screen
400 in one direction is the display area 421. More specifically, a rectangular area
determined by a distance X from the display instruction button 411a to an end of the
operation screen 400 in the right direction and a width Y of the operation screen
400 in the up-down direction is secured as the display area 421.
[0092] In Figs. 6A to 9, this display area 421 is indicated by a broken line.
[0093] Further, Fig. 6B illustrates an example of the display area 421 in a case where the
downward direction is determined as the one direction in step S504. In this case,
the display control unit 103 secures a rectangular area determined by a distance Y
from the display instruction button 411a to an end of the operation screen 400 in
the downward direction and a width X of the operation screen 400 in the right-left
direction as the display area 421.
[0094] In this manner, the display control unit 103 secures a rectangular area determined
by the distance from the specific area to the end of the operation screen 400 in one
direction and the width of the operation screen 400 in a direction intersecting with
the one direction as the display area 421.
[0095] Next, the display control unit 103 determines a size for displaying the confirmation
image 420a based on a size of the secured display area 421 (step S506). More specifically,
in the display area 421, which is an area from the specific area to the end of the
operation screen 400 in one direction, a display magnification of the confirmation
image 420a is determined so that the entire confirmation image 420a is displayed in
the largest size.
[0096] In the present exemplary embodiment, the display magnification of the confirmation
image 420a is determined so that the entire confirmation image 420a can be displayed
in consideration of margins Ma and Mb in the display area 421 in the up-down direction
and right-left direction. This margin is a margin provided along four sides inside
the display area 421, and the confirmation image 420a is displayed in a portion excluding
the margins from the display area 421. As illustrated in Fig. 9, which will be described
below, in another exemplary embodiment, it is possible to perform control so that
the confirmation image 420a can be displayed on the entire display area 421 without
providing this margin.
[0097] In Figs. 6A to 8B, the portion obtained by excluding the margin from the display
area 421 is indicated by an alternate long and short dash line.
[0098] For example, in a case of displaying the vertically long confirmation image 420a
in the display area 421, the display control unit 103 calculates a display magnification
at which the width Y - 2Ma, which is obtained by excluding the margin Ma in the up-down
direction from a height Y of the display area 421 and the height of the confirmation
image 420a coincide with each other, as a temporary display magnification. A width
of the confirmation image 420a at this temporary display magnification is compared
with the width X - 2Mb, which is obtained by excluding the margin Mb in the right-left
direction from the width X of the display area 421. In a case where the width of the
confirmation image 420a at the temporary display magnification is equal to or less
than X - 2Mb, the entire confirmation image 420a can be displayed, so that the calculated
temporary display magnification is determined as the size for displaying the confirmation
image 420a. Further, in a case where the width of the confirmation image 420a at the
temporary display magnification is more than the X - 2Mb, at least a part of the confirmation
image 420a protrudes, so that a display magnification at which the width of the confirmation
image 420a and X - 2Mb coincide with each other is recalculated, and is determined
as the size for displaying the confirmation image 420a.
[0099] Further, for example, in a case of displaying the horizontally long confirmation
image 420a in the display area 421, the display control unit 103 calculates a display
magnification at which the width X - 2Mb, which is obtained by excluding the margin
Mb in the right-left direction from the width X of the display area 421 and the width
of the confirmation image 420a coincide with each other, as the temporary display
magnification. The width of the confirmation image 420a at this temporary display
magnification is compared with the width Y - 2Ma, which is obtained by excluding the
margin Ma in the up-down direction from the height Y of the display area 421. In a
case where the height of the confirmation image 420a at the temporary display magnification
is equal to or less than Y - 2Ma, the calculated temporary display magnification is
determined as the size for displaying the confirmation image 420a. In a case where
the height of the confirmation image 420a at the temporary display magnification is
more than Y - 2Ma, the display magnification at which the width of the confirmation
image 420a and X - 2Mb coincide with each other is recalculated and determined as
the size for displaying the confirmation image 420a.
[0100] Further, in step S507, the display control unit 103 determines a position for displaying
the confirmation image 420a, based on a position of the specific area 416.
[0101] For example, as illustrated in Fig. 7A, in a case where one direction is the right
direction and the width of the confirmation image 420a is less than X - 2Mb at a display
magnification in which Y - 2Ma and the height of the confirmation image 420a coincide
with each other, margins are generated in the right-left direction of the confirmation
image 420a. In this case, the display control unit 103 determines a position close
to the specific area 416 as the position for displaying the confirmation image 420a.
That is, in an area illustrated by the alternate long and short dash line in Fig.
7A, the confirmation image 420a is controlled to be displayed in a left-justified
manner. Further, as illustrated in Fig. 7B, in a case where the one direction is the
downward direction, and the height of the confirmation image 420a at the display magnification
at which X - 2Mb and the width of the confirmation image 420a coincide with each other
is less than Y - 2Mb, margins are generated in the up-down direction of the confirmation
image 420a. In this case, the display control unit 103 determines a position close
to the specific area 416 as the position for displaying the confirmation image 420a.
That is, in an area illustrated by the alternate long and short dash line in Fig.
7B, the confirmation image 420a is controlled to be displayed in a top-justified manner.
[0102] In this manner, in a case where a margin is generated in a direction parallel to
the one direction, the display control unit 103 controls so that the confirmation
image 420a is displayed closer to the specific area 416.
[0103] Further, for example, as illustrated in Fig. 8A, in a case where one direction is
the right direction and the height of the confirmation image 420a at a display magnification
in which X - 2Mb and the width of the confirmation image 420a coincide with each other
is less than Y - 2Ma, margins are generated in the up-down direction. In this case,
between ends of the operation screen 400 in the up-down direction, the display control
unit 103 determines a position closer to the end in the upward direction closer to
the specific area 416 as a position for displaying the confirmation image 420a. That
is, in an area illustrated by the alternate long and short dash line in Fig. 8B, the
confirmation image 420a is controlled to be displayed in a top-justified manner.
[0104] In this manner, in a case where a margin is generated in a direction orthogonal to
the one direction, between the ends of the operation screen 400 in the orthogonal
direction, the display control unit 103 controls the confirmation image 420a to be
displayed closer to the end closer to the specific area.
[0105] As described above, by controlling the position at which the confirmation image 420a
is displayed based on the position of the specific area, it becomes easy to understand
a correspondence between the instruction image such as the document icon 410a and
the displayed confirmation image 420a.
[0106] Further, for example, as illustrated in Fig. 8B, in a case where one direction is
the up-down direction and the width of the confirmation image 420a is less than Y
- 2Ma, margins are generated in the right-left direction. In this case, the display
control unit 103 may be configured to determine the position for displaying the confirmation
image 420a at a center in the right-left direction.
[0107] Next, the confirmation image output unit 105 takes out the confirmation image 420a
from the image acquisition unit 106, and outputs the confirmation image 420a to the
display unit 40 to display the confirmation image 420a in the one direction, in the
size, and at the position determined in steps S504, S506, and S507 (step S508) . In
the example in Fig. 5B, the confirmation image 420a is displayed in the right direction
of the document icon 410a, in the size at which the height of the confirmation image
420a and Y - 2Ma are equal to each other, and at the position close to the specific
area (the display instruction button 411a).
[0108] As illustrated in Fig. 5B, the confirmation image 420a may be displayed to be superimposed
on at least a part of the other document icons 410b and 410c or toolbar 430 displayed
on the operation screen 400.
[0109] Further, the confirmation image 420a may be displayed to be superimposed on at least
a part of the document icon 410a depending on the direction or the size, the position
for displaying the confirmation image 420a, with or without the margin or the size
of the display area 421, and the like. For example, as illustrated in Fig. 9, in a
case where the specific area 416 (the display instruction button 411a) is located
in the upper right corner portion of the document icon 410a and one direction is the
left direction, the display control unit 103 displays the confirmation image 420a
to be superimposed on a part of the document icon 410a and not to be superimposed
on the display instruction button 411a.
[0110] Fig. 9 illustrates a display example in a mode in which a margin is not provided
in the display area 421. Therefore, the confirmation image 420a is displayed in a
size at which the height of the confirmation image 420a and the width Y of the display
area 421 in the up-down direction coincide with each other.
[0111] In this manner, the confirmation image 420a may be displayed at a position at which
the confirmation image 420a is superimposed on at least a part of the document icon
410a. With this configuration, as compared with a case where the confirmation image
is displayed at a position at which the confirmation image is not superimposed on
the document icon 410a, it is possible to increase the display area 421 secured for
displaying the confirmation image 420a.
[0112] Further, regardless of a case where the display instruction button 411a is displayed
in association with the specific area 416 as in the present exemplary embodiment or
a case where the display instruction button 411a is displayed without being associated
with the specific area 416, the confirmation image 420a may be displayed at a position
at which the confirmation image 420a is not superimposed on the display instruction
button 411a on the document icon 410a. With such a configuration, the user can easily
recognize a document which the user operates with a display instruction button. In
a case where the display instruction button 411a is changed to the maintenance instruction
button 412a, the maintenance instruction button 412a becomes easier to operate.
[0113] Subsequently, the instruction button output unit 104 outputs and displays the maintenance
instruction button 412 to the display unit 40 (step S509). The maintenance instruction
button 412 accepts that the display of the confirmation image 420 is set to the display
maintenance state. For example, in a case where the display instruction button 411a
illustrated in Fig. 5B is designated and the confirmation image 420a is displayed,
the display instruction button 411a is changed to the maintenance instruction button
412a illustrated in Fig. 10 and displayed.
[0114] Subsequently, the operation determination unit 101 determines whether or not the
maintenance instruction button 412 is designated (step S510). In the present exemplary
embodiment, the operation determination unit 101 determines, for example, a click
operation on the maintenance instruction button 412 as designation on the maintenance
instruction button 412.
[0115] In a case where the maintenance instruction button 412a is not designated in this
step S510 (NO in step S510), the process waits until the maintenance instruction button
412a is designated. In a case where the maintenance instruction button 412a is designated
(YES in step S510), the display control unit 103 shifts to the display maintenance
state (step S511). In the example illustrated in Fig. 10, after the maintenance instruction
button 412a is designated by a click operation, the display of the confirmation image
420a is in the display maintenance state, and the display of the confirmation image
420a is maintained even in a state in which the cursor 200 is not located over the
display instruction button 411a or the maintenance instruction button 412a.
[0116] Here, a scroll operation or the like may be performed over the operation screen 400
in the display maintenance state, and the document icon 410a may be moved. In the
present exemplary embodiment, even in a case where the document icon 410a is moved,
the size and the position of the confirmation image 420a maintain the settings when
shifting to the display maintenance state. For example, as illustrated in Fig. 10,
in a case where the document icon 410a shifts to the display maintenance state while
the document icon 410a is at a position A, even in a case where the document icon
410a then moves to a position B, the size and position of the confirmation image 420a
are not changed.
[0117] Next, the operation determination unit 101 determines whether or not an operation
of canceling the display maintenance state is performed (step S512). The operation
determination unit 101 according to the present exemplary embodiment determines, for
example, performing a click operation at a position other than the display area 421
or a click operation on the maintenance instruction button 412a again, as the operation
of canceling the display maintenance state. In a case where the canceling operation
is not performed (NO in step S512), the display maintenance state is continued. In
a case where the canceling operation is performed (YES in step S512), the display
control unit 103 cancels the display maintenance state of the confirmation image 420a
(step S513) .
[0118] The process of displaying the confirmation image 420a is completed according to the
above processing procedure.
[0119] As described above, the image display apparatus 1 according to the present exemplary
embodiment determines one direction according to a distance from the document icon
410a to ends of the operation screen 400 in the up-down direction and right-left direction,
and controls the confirmation image 420a to be displayed in the one direction from
the specific area 416 on the document icon 410a, in a case where the display of the
confirmation image 420a is instructed from an operation of the user.
[0120] Although Figs. 2 and 5A to 10 and the like illustrate an example in which the confirmation
image 420a is displayed larger than the corresponding document icon 410a, in a case
where the operation screen 400 is small, the confirmation image 420a may be displayed
smaller than the document icon 410a.
[Procedure to Determine One Direction]
[0121] Next, a procedure of determining one direction will be described in detail with reference
to Figs. 11 and 12.
[0122] Fig. 11 is an example of the operation screen 400 for explaining the procedure of
determining the one direction. Further, Fig. 12 is a flowchart illustrating an example
of the procedure of determining the one direction.
[0123] Here, as illustrated in Fig. 11, a distance from a reference position 415a at an
upper left corner portion of the document icon 410a to an end of the operation screen
400 in the left direction is defined as Xa, and a distance from the reference position
415a to an end of the operation screen 400 in the upward direction is defined as Ya.
Further, a distance from a reference position 415b at a lower right corner portion
of the document icon 410a to an end of the operation screen 400 in the right direction
is defined as Xb, and a distance from the reference position 415b to an end of the
operation screen 400 in the downward direction is Yb.
[0124] Further, a distance from the predetermined specific area 416 on the document icon
410a to the end of the operation screen 400 in the left direction is defined as Xa',
a distance from the predetermined specific area 416 to the end in the right direction
is defined as Xb' , a distance from the predetermined specific area 416 to the end
in the upward direction is defined as Ya', and a distance from the predetermined specific
area 416 to the end in the downward direction is defined as Yb'. In the present exemplary
embodiment, the display instruction button 411a is displayed in association with the
specific area 416. As illustrated in Fig. 11, the distances from the display instruction
button 411a to the ends of the operation screen 400 in the right-left direction and
up-down direction are Xa' , Xb', Ya', and Yb'.
[0125] Further, in the following description, for convenience, the operation screen 400
may be divided into four areas of "upper left", "lower left", "upper right", and "lower
right". As illustrated in Fig. 11, the "upper left", the "lower left", the "upper
right", and the "lower right" respectively correspond to areas divided by a broken
line that divides the operation screen 400 into two equal parts in the right-left
direction and a broken line that divides the operation screen 400 into two equal parts
in the up-down direction.
[0126] First, the distance determination unit 102 acquires the distances Xa, Ya, Xb, and
Yb from the reference positions 415a and 415b of the document icon 410a to the ends
of the operation screen 400 (step S601).
[0127] Next, in step S602, the distance determination unit 102 determines whether or not
Xa ≤ Xb is satisfied. In a case of Xa ≤ Xb (YES in step S602), the process proceeds
to step S603 to determine whether or not Ya ≤ Yb is satisfied. In a case of Ya ≤ Yb
(YES in step S603), it is determined that the document icon 410a is in the "upper
left" of the operation screen 400 (step S604) .
[0128] Further, in step S605, regarding the distance Xb' from the specific area 416 to the
end of the operation screen 400 in the right direction and the distance Yb' from the
specific area 416 to the end in the downward direction, the distance determination
unit 102 determines whether or not Yb' ≤ Xb' is satisfied. In a case of Yb' ≤ Xb'
(YES in step S605), the display control unit 103 determines that the one direction
is the "right" direction (step S606) . In a case where Yb' ≤ Xb' is not satisfied
(Yb'> Xb') (NO in step S605), the display control unit 103 determines the one direction
is the "downward" direction (step S613).
[0129] In a case of Ya ≤ Yb is not satisfied in step S603 (NO in step S603), the distance
determination unit 102 determines that the document icon 410a is in the "lower left"
of the operation screen 400 (step S607).
[0130] Next, in step S608, it is determined whether or not Xb'≤ Ya' is satisfied. In a case
of Xb'≤ Ya' (YES in step S608), the display control unit 103 determines that the one
direction is the "upward" direction (step S609). In a case where Xb' ≤ Ya' is not
satisfied (Xb' > Ya') (NO in step S608), the display control unit 103 determines that
the one direction is the "right" direction (step S606).
[0131] Further, in a case where Xa ≤ Xb is not satisfied (Xa > Xb) (NO in step S602), the
process proceeds to step S610 to determine whether or not Ya ≤ Yb is satisfied. In
a case of Ya ≤ Yb (YES in step S610), it is determined that the document icon 410a
is in the "upper right" of the operation screen 400 (step S611).
[0132] In step S612, it is determined whether or not Xa'≤ Yb' is satisfied. In a case of
Xa'≤ Yb' (YES in step S612), the display control unit 103 determines that the one
direction is the "downward" direction (step S613). In a case where Xa'≤ Yb' is not
satisfied (Xa'> Yb') (NO in step S612), the display control unit 103 determines that
the one direction is the "left" direction (step S616).
[0133] In a case where Ya ≤ Yb is not satisfied (Ya> Yb) (NO in step S610), the distance
determination unit 102 determines that the document icon 410a is in the "lower right"
of the operation screen 400 (step S614).
[0134] In step S615, it is determined whether or not Ya' ≤ Xa' is satisfied. In a case of
Ya' ≤ Xa' (YES in step S615), the display control unit 103 determines that the one
direction is the "left" direction (step S616). In a case where Ya' ≤ Xa' is not satisfied
(Ya' > Xa') (NO in step S615), the display control unit 103 determines that the one
direction is the "upward" direction (step S609).
[0135] With the above procedure, the process of determining the one direction is completed.
[0136] In the present exemplary embodiment, based on the distances Xa, Xb, Ya, and Yb from
the reference positions 415a and 415b to the ends of the operation screen 400, the
position of the document icon 410a is determined. Further, any two distances among
the distances Xa', Xb', Ya', and Yb' from the specific area 416 to the ends of the
operation screen 400 are compared with each other to determine one direction. In another
exemplary embodiment, the distances Xa, Xb, Ya, and Yb may simply be compared and
a direction corresponding to the largest distance may be determined as the one direction.
Further, for example, the distances Xa', Xb', Ya', and Yb' may be simply compared,
and a direction corresponding to the largest distance may be determined as the one
direction.
[Modification Example 1 of Procedure of Determining One Direction]
[0137] In the present exemplary embodiment described above, the predetermined specific area
416 and the two reference positions 415a and 415b different from the specific area
416 are provided on the document icon 410a. Based on the distance from the specific
area 416 to the ends of the operation screen 400 and the distance from the reference
positions 415a and 415b to the ends of the operation screen 400, one direction for
displaying the confirmation image 420a is determined.
[0138] In Modification Example 1 of the procedure of determining the one direction, a reference
position 415c is provided inside the specific area 416, and one direction is determined
based on a distance from the reference position 415c to an end of the operation screen
400.
[0139] Fig. 13 is a diagram illustrating Modification Example 1 of the procedure of determining
the one direction.
[0140] In Fig. 13, the display instruction button 411a is displayed in association with
the specific area 416, and the reference position 415c is further provided in the
specific area 416. Also in this case, based on distances Xc, Xd, Yc, and Yd from the
reference position 415c to ends of the operation screen 400 in the up-down direction
and the right-left direction, it is determined in which of "upper left", "lower left",
"upper right", and "lower right" areas of the operation screen 400 the document icon
410a is located. Distances from the specific area 416 to the end of the operation
screen 400 in the two directions determined from the position of the document icon
410a are compared with each other, so that it is possible to determine a direction
having a larger distance as the one direction. Further, it is possible to simply compare
the distances Xc, Xd, Yc, and Yd, and determine a direction corresponding to the largest
distance as the one direction.
[0141] As illustrated in Fig. 13, the reference position 415c is provided in the specific
area 416, and the display instruction button 411a is displayed in association with
the specific area 416, so that the user can easily predict a position and a size of
the confirmation image 420a.
[Modification Example 2 of Procedure of Determining One Direction]
[0142] Next, in Modification Example 2 of the procedure of determining the one direction,
the one direction is determined based on a distance from the specific area 416 to
an end of the operation screen 400 without providing a reference position.
[0143] Fig. 14 is a diagram illustrating Modification Example 2 of the procedure of determining
the one direction.
[0144] In Modification Example 2, the specific area 416 is defined so as to correspond to
an area in which the document icon 410a is displayed. In this case, for example, distances
Xc', Xd', Yc', and Yd' from ends of the document icon 410a in the up-down direction
and the right-left direction to ends of the operation screen 400 in the same direction
are compared with each other, so that it is possible to determine a direction corresponding
to the largest distance as the one direction.
[0145] As described above, a method of obtaining the distance from the instruction image
such as the document icon 410a to the end of the operation screen 400, which is used
to determine the one direction, can have various modes. More specifically, a distance
or the like from each side of the instruction image in the up-down direction and right-left
direction, a predetermined specific area on the instruction image, a reference position
predetermined on the instruction image, or the like to the end of the operation screen
400 in the up-down direction and right-left direction is obtained.
[0146] In the present exemplary embodiment described above, the example is illustrated in
which the entire confirmation image 420a is displayed in the maximum size determined
by the distance from the reference position 415 or the specific area 416 to the end
of the operation screen 400. Here, for example, a prototype image that is a prototype
of the confirmation image 420a may be a small image such as data obtained by scanning
a business card, so a width and a height of the display area 421 may be larger than
this prototype image. At this time, the confirmation image 420a is displayed in a
size exceeding a size appropriate for confirming the document icon 410a, and an operation
of the user on the operation screen 400 may be hindered.
[0147] Therefore, the size of the displayed confirmation image 420a may be determined based
on a size of the prototype image which is the prototype of the confirmation image
420a. For example, in the process of determining the size for displaying the confirmation
image 420a, it is possible to acquire the size (width and height) of the prototype
image from pixel information or the like, and to set the size as an upper limit of
the size (width and height) of the displayed confirmation image 420a.
[0148] Further, in the present exemplary embodiment, by designating the display instruction
button 411a and the maintenance instruction button 412a, the confirmation image 420a
is displayed or the display is shifted to the display maintenance state, and the present
exemplary embodiment is not limited thereto. The display of the confirmation image
420a or the instruction to shift to the display maintenance state may be performed
by another operation using a pointing device such as a mouse, or another user operation
such as a key input operation.
[0149] The process performed by the image display apparatus 1 according to the present exemplary
embodiment is prepared, for example, as a program such as application software. The
program can be provided by a communication section as well as provided by being stored
in a recording medium such as a CD-ROM or the like.
